WAC 194-37-190
Documentation of financial
path -- Substitute resource and resource equivalence. (1) In
support of its annual filings to the department under RCW 19.285.070, utilities must document the type, availability,
and cost of the reasonably available substitute resource used
to calculate the incremental cost of an eligible renewable
resource.
(a) In documenting the incremental cost under RCW 19.285.050 (1)(b), a utility is encouraged to identify
substitute resources using its integrated resource planning
process, if one is available. If a utility elects to choose a
substitute resource from a different source other than its
most recently published integrated resource plan, it must
document the basis for this decision. Documentation of the
cost of a substitute resource may include, but is not limited
to, formal offers for the sale of electricity, or published
cost projections from reputable third-party sources.
(b) In its selection of a substitute resource, the
utility shall develop documentation demonstrating that the
substitute resource satisfies the requirements set forth in
RCW 19.285.050. The requirements are:
(i) Equivalence between the eligible renewable resource
and the substitute resource by demonstrating the equivalence
in the amount of energy produced by each resource;
(ii) Equivalence between the eligible renewable resource
and the substitute resource by demonstrating the same contract
length or facility life of each resource;
(iii) The substitute resource is reasonably available to
the utility; and
(iv) The substitute resource does not qualify as an
eligible renewable resource.
(c) Only supply-side substitute resources shall be used
by utilities in the calculation of the incremental cost of
eligible renewable resources.
(d) When the renewable requirements under RCW 19.285.040(2) result in a utility having resources in excess
of its load, the utility may use that excess resource as the
substitute resource if the substitute resource requirements of
(b) of this subsection are otherwise satisfied. The utility
will document the resale revenues, net of transaction costs,
received through the sale of excess resources or the purchase
price for the sale of the excess facility sold as a result of
the requirement to acquire eligible renewable resources. A
utility that uses a value other than the documented resale
revenue in the determination of the levelized delivered cost
of the substitute resource, such as a forecast of projected
market prices, must provide documentation to support this
alternative approach.
(e) A utility may use foregone power purchases from BPA,
plus any billing credit obtained for reducing its purchases
from BPA, as the basis for the cost of the substitute resource
if:
(i) The substitute resource requirements of (b) of this
subsection are otherwise satisfied;
(ii) It is entitled under its BPA power sales contract to
have the BPA meet its net power requirements for the expected
life of an eligible renewable resource or eligible renewable
resource purchase; and
(iii) As a result of meeting the renewable requirements
under RCW 19.285.040(2), it foregoes part of its BPA
entitlement in order to obtain that eligible renewable
resource.
(2) For an eligible renewable resource acquired prior to
the passage of chapter 19.285 RCW, November 7, 2006, a utility
must support the selection of the related substitute resource
used in the determination of the incremental cost under RCW 19.285.050 with documentation that was available at the time
of the utility's decision to acquire the eligible renewable
resource. If no such documentation is available, the
incremental cost of an eligible renewable resource acquired
prior to the passage of chapter 19.285 RCW will be assumed
equal to zero.
